Calibration is done using our up to date calibration instruments. All measurements are traceable to the standards at the National Physical Laboratory. We will typically perform in excess of 70 test point measurements, and provide a written report with % accuracy against manufacturers specifications. (with a plain english explanation of anything noteworthy).... (Some calibration labs will only take a few point measurements which gives a less in-depth understanding of your tester's true performance across it's whole range and all it's functions).

We will provide a computer generated, certificate of calibration with the returned instrument, with all test performance figures clearly stated.

In the unlikely event that the tester does not pass, it can be returned with a report. Repairs are not included, but we can arrange repairs at discounted rates, and re-test will be free.

When you send your tester to us, please ensure it is well packed and insured. If you prefer, We can send Parcelforce to collect your tester for an extra 15 pounds (24 hour delivery), but you will need to pack it up ready for collection. (email us before paying if you would like us to arrange collection and we can send a paypal invopice for the total cost)

We understand that your tester is critical to your business. We will process the calibration straight away and get it back to you quickly. In the unlikely event that there are any problems, We will help you get them sorted with a minimum of fuss.
